The UWGB Retiree Association is sponsoring the eighth annual arboretum/bird walk on Tuesday, May 15 at 10:45 a.m. A Cofrin Center for Biodiversity employee will lead the walk. Interested participants should meet at the Lambeau Cottage parking lot at 10:30 a.m. The walk will be slow and easy as the group looks to identify spring plants and wildlife. Bring your binoculars, bird/plant book or camera. Meet at the Shorewood Club for lunch if you so wish.
